Definition
These pins are the reference voltage pins for the analog-to-digital
converter (ADC).
These pins are the power supply pins for the analog-to-digital converter.
These pins are the ground and power supply pins, respectively. The
MCU operates from a single power supply.
These pins are special function, bidirectional I/O port pins that are
shared with other functional modules in the MCU.

For test purposes only. Do not connect in the application.
This pin allows the enabling and PWM control of the high side HS1 and
HS2 pins.
This pin is the reset output pin of the analog die.
This pin is the interrupt output pin of the analog die indicating errors or
wake-up events.
These pins are the wake-up inputs of the analog chip.
These output pins are low R

These pins are device power supply pins.
This pin represents the single-wire bus transmitter and receiver.
These pins are device power ground connections.
The + 5.0 V voltage regulator output pin is intended to supply the
embedded microcontroller.
This pin is the single +5.0 V power supply for the current sense
operational amplifier.
This pin is the output of the current sense operational amplifier.
These pins are the current sense operational amplifier inverted and
non-inverted inputs.
This input pin is for configuration of the watchdog period and allows the
disabling of the watchdog.
This pin is the output of LIN transceiver.
